This invention relates to improvements in radio logs.

It is one of the objects of the present 1nvention to provide a handy log for use with radio machines. A further object of the invention isto provide a radio log which can always be kept4 1n juxtaposition to the radio, or attached thereto, and which will tell ata l settings of desired stations. j

A further object of the invention 1s to proi vide a novel `form of radio log which is ornamental in appearance. Y y

A further object of the invention 1s to provide a radio logwhich is of very simple construction, is inexpensive to manufacture, is easy to manipulate, and is well adapted for the purpose described.

With the above and other objects in view Y the invention consists of the improved radio log, and its parts andcombinations as set forth in the claims and all equivalents thereof. Y

In the accompanying drawing in which the ysame reference characters indicate the same parts in all of the views:

Fig. 1 is a plan view ofthe improved radio log associated with a radio; Y

Fig. 2 is an enlarged fragmentary view of the log; o Fig. 3 is a view taken on line 3-3 of Fig. 2; and

Fig. 4 is a sectional view taken on lino 4-4 of Fig. 3. y 1 Referring now more particularly to the drawing it 'will be seen that the device is formed of an elongated rectangular block or base 6 formed'of woodor other suitable material and having Vits `lower surface covered indicated by the numeral 7.

The upper surface of the block, except fo a strip adjacent the inner edge thereof, receives a metallic frame 8 which is bent over along its forward and side edges tooling to the block. The rear edge ofthe `frame is bent forwardly to provide a flange 9.

Covering the forwardv and side portions of the frame 8 is a metallic member 10 arranged to Vprovide a slot between it and the portion 8 of the frame for the vinsertion of indicia strips, as will later be explained.

. ybase member-an indicia strip holding mem` glance the dial The upper surface of the block, within the V'Space defined bythe frame and member 10,

1s provided with a plurality of transversely extending, adjacent members 11 forming indicia strip trays.

The rear flanged portlon 9 of the frame 8 has delineated thereon from end to end and equally spaced apart, numeral designations corresponding to the numerical ldivisions on the dials of a radio. i

Covering the inner or rea-r portion of the face of the block. and adjacent the frame 8,

Vis a guide member 12 having yoverturned edge fiangesl and said guide member isV adapted to receive in proper relation wave length tabs 14.

In use, the device may be conveniently loi cated adjacent a radio 15, as shown in Fig.v 1 and indlcla strips `16, each bearing the name,

'call letters, location, and wave length of a station, are provided. When a station is located on the radio, the indicia strip there# for is selected and the station is then logged by inserting the strip between the members `8 and 10 and into the tray registeringv with the numerical designation on the portion 9 which corresponds to the dial reading for the station. After severalstations have been thus logged, the wavelength tabs 14 which are frictionally held inthe member 12 mayy be adjusted in proper relation, and the dial settings for unfound stations may be readily estimated and the device provides a handy and attractive log for desired stations.

From the foregoing description it will be seen that the improved radio log is of'very` simple and novel construction, and is well adapted for the purposes set forth.

What I claim as my invention is:

1. In combination, an elongated straight ber thereon, a wave length tab holding member thereon, a plurality of wave length tabs longitudinally removably mounted therein in properspaced relation, and a plurality of sta-tion indicia strips engaged by said first mentioned holding member and movable at right angles toV the direction of movement of the wave lengt-h tabs, said strip holding member 'being provided with dial setting graduati ons and said strips and tabs being in register with predetermined graduations.`

2. A radio logging device, comprising an ber inwardly of said trays and at. right anelongated base member, a plurality of adja- ,files thereto. and ware lengtli talis mounted eent, transversely extending trays mounted in said guide member and m( vable tlierein 10 on the upper surface of the base member, at right angles to said station indicia strips.

5 station indicia strips removably engaged by In testimony whereof, I atlix my signature.
